On the Fence Words~!

Whats with people that use words that are on both sides of the fence? It makes their point hazy. Is it because they don't want to feel wrong? Words like, Might, Kind Of, Sort Of, Maybe, Don't Know, Also, But, Sometimes, Guess, Suppose...

Can't think of much else right now. I myself use these words. I'm trying not to. It just makes sentances long and unclear. It's one of my pet peeves.
